The 1.5-minute film titled "An Ode to Lahore, the Beautiful City" opens with a shot of the famous Badshahi mosque before showing images from the popular park where a Taliban suicide bomber blew himself up in an attack targeting Christians on Easter Sunday.
At least 72 people died in the blast as families enjoyed the warm spring evening, many of them children. The bomber had walked close to a play area with swings before detonating.
Her video, posted yesterday, showed old images of the play area before Sunday's devastation, as well as footage from a candle-lit vigil that took place for the victims in Lahore.
"Lahore used to teach you to make bridges in order to reach each other," a female voiceover says in Urdu as the images flit by.
